hmmm if you write something new maybe psr4 standards would be nice. and I'm not sure about the view concept esp. since your views don't seam to be very modular.
I'm writing my php framework now for 8 years not because I want to have a simple version more out of academic curiousity and you seam to write before you create a concept.
which is cool, but if you continue this path you will, very likely throw most of it away :) (i am at version 3.0 which are basically only libraries that are unittested and composed with a DI but my first attempt was partial like yours)
anyhow :) cool work! keep going :) there is a lot of fun ahead of you :)
